Rustic bunting Ocyris rusticus in the Vishersky and Norsky strict nature reserves

Abstract

The Information about the state and the dynamics of the number of the local nesting population of the Rustic bunting in the Visherky strict nature reserve of the Perm Region is given. The average population density of Ocyris rusticus on the territory of the strict nature reserve in the nesting period, according to data until 2014, is: 1.5±1.2 pairs/km2 in mountain taiga forests, and 1.4±1.1 pairs/km2 in valley forests. A comparison is made with the Norsky strict nature reserve of the Amur Region, where the species occurs on migration, and the dynamics of the number of migratory birds is analyzed. The validity of including the species in the Red Books of the Russian Federation and regions is discussed.
